Replacement of camera glass with Xiaomi Redmi: disassemble the phone without the risk of damaging the module

Broken camera glass on Xiaomi Redmi is a problem that many smartphone owners face. Even a minor crack can spoil photos, create glare and reduce the quality of shooting. The service center will take from 1,500 to 3,000 rubles for a replacement, but with tools and accuracy, you can do the procedure yourself, the main thing is not to damage the camera module or the plumes inside the phone.

In this article, we will discuss how to remove the Redmi back cover, dismantle old glass, install a new one and reassemble the device, focus on the selection of glue, temperature during disassembly and check the health after repair, and find a list of necessary tools, tips for buying spare parts and answers to frequent questions.

Warning: Repairs require patience and precision, if you've never taken your smartphone apart, practice on an old device or watch video instructions before you start work, and errors can lead to loss of sealed housing or damage to internal components.

Which Xiaomi Redmi models are subject to self-replacement of camera glass?

The camera glass replacement technology is almost the same for most Xiaomi Redmi models, but there are nuances depending on the design of the case.

• 📱 Redmi Note 10/10 Pro/10S — glass is attached to glue, the camera module is not soldered to the board.
• 📱 Redmi Note 11/11 Pro/11T — similar design, but requires a more accurate separation of the plume.
• 📱 Redmi 9/9A/9C/9T — easy disassembly, but the glass often comes complete with the camera cover.
• 📱 Redmi 12/12C — The new generation, but the principle of replacement has not changed.

More challenging are the Redmi K flagships (like the K50 or K60): their bodies often have additional mounts, and camera modules can be integrated into a metal frame. If your model is not included in the list, check out its features on forums (for example, 4PDA or MIUI Russia).

⚠️ Note: On models with a mobile camera (e.g. Redmi) K30 Pro Zoom) self-replacement of glass is fraught with failure of the mechanism.

Tools and materials: what you need to replace

Before you start repairing, prepare everything you need, and the quality of the tools will determine the success of the operation.

In addition, the following may be useful:

• 🔧 Screwdriver. T3/T4 — to unscrew the screws (if you have them in your model).
• 🧴 Isopropyl alcohol (90%+) — glue-cleaner.
• 📏 Tweezers to keep the small details carefully.
• 🕯️ UV lamp – if you use UV glue (optional).

⚠️ Warning: Do not use metal blades or knives - they will scratch the body and can damage the plumes. Also avoid overheating with a hairdryer: temperature above 90°C deforms plastic and damages the battery.

💡

Before buying glass, check its article for your model. For example, for the Redmi Note 10 Pro, the original glass is labeled MDY-11-21. Analogues may differ in thickness and color!

Step-by-step: how to remove the back cover and get to the glass

The most important step is to carefully separate the back panel, and in most Xiaomi Redmi models, it is glued around the perimeter, and inside it can be latches.

1. Turn off the phone and remove it. SIM-Memory card (if there is a slot).
2. Heat the body with a hair dryer around the perimeter for 2-3 minutes. Keep the hair dryer at a distance of 5-7 cm, so as not to overheat the battery.
3. Install the suction cups at the bottom of the phone (near the USB-C connector) and pull up slightly.
4. Insert a plastic blade into the resulting gap and carefully lead it along the body, separating the glue.
5. Disconnect the plumes (if they interfere) - they are usually attached to the latches. Don't pull the wires!

On some models (for example, Redmi Note 11 Pro+) under the lid can be screws — they need to unscrew with a screwdriver T3. If the lid does not respond, warm up the problem areas again with a hairdryer.

⚠️ Note: On models with wireless charging (e.g. Redmi) K50) There's a coil under the lid -- don't hurt it with a spatula! Also be careful with the flexible plume of the fingerprint scanner.

Dismantling old glass and cleaning the landing site

When the lid is removed, you'll see a camera module protected by glass, which is also glued, but usually less firmly than the lid itself, to remove it.

1. Plug paint tape on the glass - this will prevent fragments from flying apart.
2. Carefully apply the glass blade from any angle. If it does not lend itself, warm up with a hair dryer for 1-2 minutes.
3. Remove the glass and remove the residues of the glue from the body and the camera module with isopropyl alcohol.
4. Check if there are any fragments inside the case - they can damage the plumes.

Clean the seat without pressing: the camera module is fragile and its lenses are easy to scratch. If the board has fibers from the napkin, remove them with tweezers or compressed air (a canister for cleaning equipment).

🔍 Tip: If old glass is shattered, use a stationery knife to gently cut the glue along the contour. Keep the knife at a 15-20 angle.° to the body so as not to scratch the plastic.

Installation of new glass: glue, fixation, drying

Now you need to install a new glass, and it's critical to choose the right glue and apply it evenly.

1. Apply the adhesive around the perimeter of the seat in a thin layer. For the B-7000, a strip of 0.5 mm thick is enough.
2. Set the glass and press it for 1-2 minutes. Make sure it sits smoothly, without skewing.
3. Remove excess glue with a napkin soaked in alcohol.
4. Secure the glass with tape for 12–24 hours (if you use the B-7000) or illuminate with a UV lamp for 2–3 minutes (for UV glue).

Important: don't turn on your phone and press the glass until the glue is completely dry! For the B-7000, it's 24 hours, for the LOCTITE 406, it's 4-6 hours. If the glass walks after installation, then there's not enough glue, you'll have to redo it.

📌 Check tightness: After drying the glue, check if dust is falling under the glass. To do this, direct a bright light to the camera - if you see gaps, apply an additional layer of glue around the edges.

💡

Use only specialized adhesives for electronics (B-7000, LOCTITE). superglue or moment crystallize and can damage the plastic on the next repair.

Assembly of the phone and checking of performance

When the glue is dry, you just have to put the phone back together.

1. Connect all the plumes (if disconnected) and make sure they get into the connectors before clicking.
2. Install the back cover and warm it up with a hair dryer around the perimeter (60°C) so that the glue catches.
3. Press the lid for 1-2 minutes (you can use a heavy book).
4. Then, put the sleeves in the back.

After assembly, turn on the phone and check:

• 📸 Quality of photos - whether there are glare or blurring.
• 🔋 Charging - sometimes after disassembly, the battery contact is broken.
• 📶 Sensors (print, approach) - they could shift.

⚠️ Warning: If the phone doesn't turn on after assembly, check the battery and power plume connection. A common error is a compressed or torn display plume that leaves the screen black.

Frequent Mistakes and How to Avoid Them

Even with a careful repair, you can make mistakes that will lead to new problems.

Another common problem is water resistance loss: If your Redmi had IP53 protection (like the Redmi Note 11 Pro+), it will disappear after self-repair, and to partially restore protection, use an electronic sealant (like the Dow Corning 704) on the edges of the lid.

💡 Tip: If the camera becomes less photographic after changing the glass, check if there is any dust or traces of glue under the glass. The camera module may also have shifted, in which case you will need to re-disassemble.
